SW-157B Polyester Dust-Free Wiping Polyester Swab

Product Overview

The SW-157B is a long-handle polyester dust-free wiping swab with an ultra-fine knitted polyester microfiber head, constructed for precision surface cleaning on sensitive substrates — optical lenses, display screens, precision instrument panels, and electronic equipment surfaces — where fiber diameter, surface scratch risk, and static charge generation are all selection criteria that standard foam or coarser polyester swabs fail to satisfy simultaneously. The ultra-fine fiber structure is woven to a fineness level that allows individual fiber ends to penetrate micro-scale surface texture features, dislodging and capturing contaminant particles from sub-surface recesses that a flat foam face would simply bridge over without contact.

The swab head measures 16.2mm in length, 7.2mm in width, and 2.7mm in thickness. The 7.2mm width provides sufficient coverage for single-pass cleaning of standard optical lens active areas, display pixel zones, and instrument panel indicator windows without requiring multiple parallel strokes. The polyester microfiber fabric delivers excellent liquid absorption and uniform release — taking up IPA or cleaning solution evenly from the fiber matrix during the wet pass, then releasing it consistently against the substrate during contact, avoiding the uneven application that causes streaking on optical surfaces.

Antistatic Treatment & Long-Handle Reach

The polyester head has undergone antistatic treatment that dissipates charge accumulation during wiping, preventing electrostatic attraction of airborne dust back to the just-cleaned optical surface — a failure mode that commonly defeats standard wipe-cleaning procedures on glass and polished polymer substrates where the wiping action itself generates triboelectric charge. This antistatic characteristic makes the SW-157B suitable for cleaning display screens, camera lenses, and electronic equipment surfaces in environments where immediate re-soiling from airborne particles after cleaning is a known problem.

The polypropylene handle extends to 160mm in total length with 3.1mm width and thickness — the longest handle in the polyester swab series — providing extended reach for cleaning optical components inside instrument housings, cleaning display panels in partially assembled device enclosures, and accessing lens elements in assembled optical systems without requiring disassembly of the instrument. The handle length also maintains hand clearance from the optical surface during cleaning, reducing the risk of fingerprint re-contamination during the wiping stroke. Package contains 100 pieces.

Industry Applications & Use Scenarios

The SW-157B is applied in optical instrument cleaning, display manufacturing, precision electronics maintenance, semiconductor equipment servicing, and laboratory instrument cleaning workflows where ultra-fine microfiber contact, antistatic performance, and extended handle reach are required together. Specific use scenarios include cleaning camera lenses and telescope objective surfaces, wiping display panel active zones during manufacturing quality inspection, removing fingerprints and oil deposits from optical filter surfaces, cleaning precision instrument indicator windows inside assembled housings, and performing final surface wipe-down on optical component assemblies before packaging. The antistatic microfiber combination makes it particularly effective on glass, polished ceramic, and anti-reflective coated surfaces where conventional cleaning leaves static-attracted dust residue after the solvent evaporates.
